A graduate student received an "F" because he did not submit his assignment on Brightspace. After he received the "F" he emailed me (the professor) and reported that he had indeed submitted the assignment on Brightspace on May 18th, but Brightspace "lost" his assignment. As the professor, I cannot see any submission from him. He is specific about May 18th. Is it possible to do an in-depth analysis of this student's activities on Brightspace on May 18th? All I can see is that he accessed the system on May 18th, but he did not access the course on May 18th.
It it possible for Brightspace to lose an assignment? I am skeptical.
